I'm 33. Great health. I have masturbated on average 2-4 times daily since discovering it at age 13. I have felt fatigued and soreness at times in those 20 years when I have either had sex or masturbated too much, both resulting in ejaculating too much. By too much I mean 5-10 or more times in 24hrs. Normally I would say 1 time a day was minimum, but on average 2-4. THere would be days that it wouldn't be practical or just didn't feel like it but then 2 times the next day or not for a couple days then 3 or 4 times in a day, sometimes back to back with no break. So with that background, I felt the same pain I felt before, kind of like almost a hernia, in the lower left abdomen area, and pain directly at the left testicle. The pain became greater after having sex and masturbating in the same day after the left one had been sore the day before. Previously I felt this and took a break for a day and it went away. I'm on day 3 of mild/medium pain, like someone is barely squeezing it, but enough to be in discomfort, i'd say a 4 or 5 on a 1-10 scale. I have felt all around and had no hard bumps or lumps or anything that would signify a hernia or lumps on either of my testicles. Also, when we did have sex, my girlfriend would sometimes squeeze or stimulate my testicles and this last time got a little too rough and squeezed too hard and it hurt, not that bad, but enough to wince and say OH my god,, EASY! so just wondering if that is too much masterbation or ejaculation and if I should rest and not masturbate for a week or so and if still in pain see a dr.
